At least 13 people were killed and 100 injured Thursday after a vehicle plowed into a crowd of people in Barcelona, Catalonian authorities said. The Islamic State claimed responsibility for the attack, which occurred when a man drove a van into pedestrians near the Plaça de Catalunya in the Las Ramblas neighborhood. Catalan police had confirmed that the incident was a terrorist attack earlier Thursday. Two suspects have been arrested in connection with the incident, and local authorities in the Catalonian town of Vic — almost due north of Barcelona — have said they identified a second van linked to the attack in Las Ramblas, The Guardian reports. Police are urging people to stay away from the area, which is a popular tourist destination.

Police in Spain announced early Friday that they shot and killed four people during a counter-terrorism raid in the coastal city of Cambrils. One additional suspect was injured. The city is south of Barcelona, and police believe the suspects were linked to the van attack that killed at least 13 people Thursday in the Las Ramblas area. Two people were arrested Thursday in connection with the Barcelona attack, but police said neither detainee is suspected of being the van's driver.

President Trump on Thursday tweeted a renewed defense of Confederate monuments, claiming, "You can't change history, but you can learn from it. Robert E. Lee, Stonewall Jackson — who's next, Washington, Jefferson? So foolish!" Trump added that "the beauty that is being taken out of our cities, towns, and parks will be greatly missed and never able to be comparably replaced!" Earlier this week, Trump claimed that the removal of Confederate monuments is "up to a local town, community, or the federal government depending on where it is located." One person was killed and more than a dozen injured in Charlottesville, Virginia, over the weekend, when white nationalist groups protested the removal of a monument of Lee, the Confederate Army general.

The Dow Jones closed Thursday afternoon down more than 274 points as investors were rattled by the chaos engulfing the Trump White House in addition to a deadly terrorist attack in Barcelona. The 1.2 percent drop in the Dow made for the index's second-worst day of the year. The Nasdaq Composite also posted a 1.9 percent slide, while the S&P 500 plunged 1.5 percent. The market was particularly spooked by the idea that former Goldman Sachs executive Gary Cohn could resign from President Trump's National Economic Council; Cohn was reportedly "disgusted" by Trump's tepid response to the white nationalist demonstrations in Charlottesville, Virginia, over the weekend, which resulted in the death of 32-year-old Heather Heyer.

21st Century Fox CEO James Murdoch wrote in a memo Thursday that President Trump's reaction to the violence at a white supremacist rally in Charlottesville last weekend should "concern all of us as Americans and free people," and shared he and his wife Kathryn will donated $1 million to the Anti-Defamation League. Murdoch, whose father is media mogul Rupert, said he doesn't usually "offer running commentary on current affairs," but was so distressed by the "acts of brutal terrorism and violence perpetrated by a racist mob" that he felt the need to comment. "I can't even believe I have to write this," he said. "Standing up to Nazis is essential; there are no good Nazis. Or Klansmen, or terrorists. Democrats, Republicans, and others must all agree on this, and it compromises nothing for them to do so."
